Luminas: common questions

What microcontroller does the Luminas use?

The Luminas is built around the STM32F411R_C-E_Tx, from the STM32 family.

How big is the Luminas PCB?

The Luminas measures 65.3 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Luminas?

72 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Luminas design files?

From the leobeo-png/Luminas repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Luminas design in my own project?

The repository has no license, so all rights stay with leobeo-png. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Luminas without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
